[FFmpeg-devel] [PATCH] [RFC] avformat/options_table: do not merge sidedata by default

[Michael Niedermayer]

This requires applications to pass side data from demuxer to
decoder and demuxer to muxer.
If we want this change then a #if MAJOR_VERSION would need to be
added around it as it adds the new requirement of passing side data
around too (through all queues an application has between its demuxer
and muxer/decoder layers)

Do applications support this kind of side data passing already ?
